NOZZLE FOR CAKE-COATING- MACHINES.

Application filed September 27, 1919.

T 0 all whom it may concern:

Be it known that I, WILLIAM COSTELLO, Jr., a citizen of the United States, residing in Philadelphia, Pennsylvania, have 1nvented' certain Improvements in Nozzles for Cake-Coating Machines, of which the following is a specification.

My invention relates to cake coating Inachinery; and the object of my invention is to provide an improved form of nozzle from which coating or icing for cakes in the form of marsh-mallow, sugar icing, elly, and material of a like nature may be discharged from a plurality of apertures.

A further object of my invention is to provide a nozzle capable of discharging through a plurality of apertures coating material of two different kinds from independent reservoirs communicating with the discharge apertures.

A further object of my invention is to provide means whereby the deposits of coating material from one source may be interspersed with the deposits of coating material from another source; either one of such sources providing the portion of the deposit centrally disposed; and a still further object of my present invention is to provide means whereby coating material from two sources may be discharged through what may be called, substantially at least, a single aperture of the nozzle.

These and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a sectional elevation of one form of nozzle within the scope of my in vention; the same being taken on the line I--I, Fig. 2, and showing an annular row of apertures in which the alternate ones are in communication with the same kind of coating material.

Fig. 12, is a horizontal section of the modification of Fig. 11, taken on the line XIIXII of that figure, and

Figs. 13 and 14, are partial horizontal sections of still further modifications, and are similar to the complete section of Fig. 12.

The nozzle to which my present improvements have been applied is of the same general type as those illustrated in my Patent No. 1,310,062, dated July 15, 1919, in which such'nozzles are shown as two-part structures; one part being carried by the bottom of the coating hopper and provided with a partition for alinement with the hopper partition so that the material from a pair of hoppers may be separately distributed to certain of the outlets of the nozzle structure, while the other part (having the outlet apertures) is detachably connected to the part carried by the bottom of the coating hopper.

l have shown in the present drawings, a bottom plate 1 arranged to receive nozzles 2 of the double compartment type (one of which is shown) said nozzle comprising a p0rti0n2 let into an aperture 1 in the bottom plate 1 and held in place by screws 3 engaging a flange 1 thereof. Said portion 2 has a discharge aperture or orifice 5, preferably centrally disposed, and a removable portion 2 preferably in threaded engagement therewith, as clearly indicated in the drawings.

I The removable portion 2 is provided with a plurality of apertures, 6, 6 and 6 for the discharge of material from the several hoppers of the coating material; the aperture 6 being centrally disposed, and the apertures 6 and 6 surrounding the aperture 6 in an annular row and alternating with each other. In the present instance, the discharge aperture or orifice 5, instead of extending to the bottom wall of the removable portion 2 delivers to an internal chamber 7 formed within said removable portion, and from this chamber lead the outlets 6 and 6 the latter being interspersed between the outlets 6 from which material within the main chamber 8 of the removable portion 2 is discharged.

; In the form of structure shown in Figs. 1, 2, ct 86Q., the wall of the chamber 7 carried by the removable portion has a central aperture 9 for the reception of the stem 10 of the portion 2 having the discharge aperture or orifice 5; said stem being shouldered at 11 and seating in the wall forming the supplemental chamber 7 so as to insure a tight joint, which may be insured by screwingthe-part 2" tightly into place.

In the liorm of nozzle shown in Figs. 1, 2, ct -sc .,-the nozzle has seven outlets; a. central outlet 6, and six outlets in an annular row surrounding the central outlet and indicated. at 6 and. 6 Three of these outlets, those marked ,6", communicate with the main chamber S of the removable member, wl'iile the other three, those n'iarked, 6?, are inclosedby and receive coatingmaterial from the supplemental chamber 7, which also supplies the aperture 6. V

It will be understood, of course, that other forms of nozzlesv having a greater or less numbenot orifices ordiseharge apertures may be employed, and in Fig. 4,1 have shown a form of nozzle wherein the removahle section is provided with e even aperture's or outlets; a central aperture 6 surrounded by ten apertures in an annular row: one form of material being d. .,.1arged through live at the apertures oi"? the annular row, while another form of material is discharged through the live other apertures oi the annular row and. the central aperture.

A turther feature within the scope otin invention is to arrange the dis-ha e outl or apertures of the removable portions 2 o the nozzles so that both kinds of mate al delivered by said nozzles may be discharged through some of thegduplerz apertures or outlets; To this end, the structure may be as illustrated in Figs. 7, 8 and 9, wherein certain of the annular row of apertures or outlets, indicated at 6, are shown as Tc -.l ing material from each chamber the re inovablepart of the nozzle.

In Fig. 10, l have shown a modified form of duplex outlet which may be employed with the torm 0t nozzle illustratedin Figs. 7, 8 and 9. In the structure as illustrator In these views, the duplex discharge outlets or apertures (3 through which the two differing coatings pass has a partition 12, usually rentrally disposed, that extends to the bottom plane 0t the wall making up such outlet, and. material discharged trom the same is deliv- .ered in substantially well. defined patches on the cake directly adjacent each other; the

line ofcleavage between them beingfquite.

clear usually, though somewhat dependent upon the consistency of the coating material. In some instances, however, it may be desirable to allow the coating material from these. independent sources to merge to a certainextent, and in Fig. 10, I have shown a form of outlet in which the partition, indicated at 12, stops short of the bottom plane of the outlet.

The forms of nozzles shown in Figs. 1, to 8,'hoth inclusive, are relatively small and are designed for operation upon relatively small cakes. It will beunderstood, of course, that nozzles may be provided with several rows of apertures for operation upon large or relatively large cakes, and in Figs-11, 12, 13 and 14,1 have shown a form of nozzle more particularly designed for the larger cakes, cookies and the like; Fig. 11,,being a sectional elevation on the line XIXI, Fig. 12; Fig. .12, being a sectional plan view on the line XII-Jill, Fig. 11, and Figs. 13 and 1 1, illustrating modifications oi the chambered portion of the part 2 of the nozzle. and showing dii'lerentarrangemei'its of the outlets for the deposit of the several coating materials, in what may be considcred special designs, on the cakes.

Fig. 11, shows a nozzlewith its removable portion 2 provided with a bulge or en larged part 13, having an extra row of aperturesgthat is to say, the structureas illustrated in Figs. 11, 1 2, 13 and 14, is pro' vided with nineteen outlets, each'ot which may be of the same size or of any convenient size and capable of any desired arrangement witl'i respect to the material to be deposited. Thus in Figs. 11 and 12, the interior of the part 2 is divided into two chambers, 7 and 8 one of which receives, the coating material from the discharge aperture or orifice 5 ot' the portion 2. of the nozzlestructure, from which it may be delivered to the cakes throi the seven central discharge outlets or apertures, while theouter chamber S is provided with twelve outlets through which lbe discharged from said chamber 7 through the seven central aperturesandthe alternate apertures of the outer row; the othermaterial. going'through the other apertures of said outer row.

14.-,.which view is on the same plane as Figs. 12 and 13, shows another modification in avhichthe material from the central chamber 7 is discharged through the central aperture and throu the alternate apertures of theouter row; the other apertures ofthe iot outer row and all of the apertures of the inner row receiving material from the other chamber, indicated at 8.

As may be readily understood, the nozzles can be constructed with discharge outlets of any character whatsoever, and the interior of the portion 2 can be divided into a pair of chambers in many difi'erent ways so that the coating material can be deposited in many different designs on the surface of the cakes or cookies when the several coatin materials differ in color.

lhe portion 2 of each nozzle has a pair ofchannels or passages 14.- and 15; one channel communicatin with the centrally disposed discharge out et 5 for delivery to the supplemental chamber 7 of the removable portion 2 while the other channel communicates with the main chamber 8 of said removable portion. Between the channels or passages 14 and 15, of the portion 2 of the nozzle, a central wall or partition 16 is provided, which must be placed in its socket or aperture l in the bottom plate 1, in line with the longitudinal axis of the same, and in such position underlyin the central partition or division plate 1 7 of the coating material receptacle.

It will be understood that the sections 2* of the nozzles may be universally interchangeable so that when the coating receptacle bottom 1 is equipped with the portions 2 of the nozzles, any of the portions 2" may be employed therewith; it merely being necessary to provide threaded engaging portions of the same size.

As in the patented structure referred to, the mechanism for forcing the material through the orifices or apertures may be arranged to effect delivery from both orifices or sets of orifices simultaneously, or from either orifice or set of orifices ahead of the other, depending entirely upon the effect which it is desired the coating material shall produce.

I claim:

1. In a nozzle, the combination with a relatively fixed portion having a plurality of channels or compartments of a distributing head detachably secured to said fixed portion and having a concentrically disposed substantially bell shaped inner partitioning wall forming an independent chamber in said head and having an opening centrally disposed in the top thereof, a duct leading from one of the compartments of the fixed portion to said central opening, another of the compartments of the fixed portion communicating with the other chamber of the distributing head, and discharge apertures in the distributing head leading from each of the chambers therein.
